"Gelhaus' role as a firearms instructor dates back to at least 1995.
In an accident that made the news that year, he shot himself in the leg with his
service handgun while holstering the gun to frisk a teen for weapons."

Yeah, everything I read about this sets this guy up as viewing himself not as a policeman, but as an infantryman in hostile territory. And as I've written in other places, the tragedy is that he'll be hung out to dry while ignoring that his attitudes were respected, even celebrated, within the institution. Thus nothing will change.
